I recently got into a project where the client wanted to import information from an Excel file into an app. I know a lot of people say, just transform it into a CSV and parse it that way, but I really didn't want the client to go through yet another step and introduce a different file format - as simple as that may be.
I tried using DHlibxls, but I felt it was a little bit too complicated, so I created QZXLSReader. It's a drag-and-drop solution so it's a lot easier to use. I don't think it's as feature complete, but it worked for me.
It's basically a library that can open XLS files and parse them into Obj-C classes. Once you have the classes, it's very easy to send them to Core Data or a dictionary or what have you.
I hope it helps!
